PATENT KARL ENGSBERG, OF NEN YORK, N. Y.

LOOM FOR WEAVING FRINGE.

SPECIFICATION forming part of Letters Patent No. 477,204, dated June 21,1892.

Application filed August 15, 1891. Serial No. 403,705. (No model.)Patented in England January 14, 1886, No. 618.

To all whom it may concern.-

Be it known that I, KARL EN GSBERG, of New York city, New York, haveinvented an Improvement in Looms for \Veavin g Fringe, (for which I haveobtained a patent in England, No. 618, dated January 14,1886) of whichthe following is aspecification.

This invention relates to an attachment to looms, by which loops formedby the shuttlethread are automatically twisted into fringes.

The invention consists in the various features of improvement more fullypointed out in the claims.

In the accompanying drawings, Figure 1 is a cross-section through a loomprovided with my improved fringe attachment. Fig. 2 is a top view of thetwister proper; Fig. 8, a side View thereof; Fig. 4, a detail top viewof the main part of the twister; Fig. 5, a cross-section on line a: a,Fig. 4:; Fig. 6, a side view of the shuttle; Fig. 7, a cross-sectionthereof. Figs. 8, 9, 10, and 11 show consecutive stages of theshuttle-thread during the formation of a fringe.

The letter (t represents a loom of suitable construction for weavingfringe.

11 is the harness, and c the lay.

The loom is provided with one or more grooved rails (Z, extending fromthe front to the rear, and in which there is free to move backward andforward a rack or toothed bar 6. This toothed bar is drawn backward andforward at regular intervals ('11. (2., at the formation of each fringe)by means of a camfand a counteracting spring g. The spring is connectedto the forward end of the rack by string g. The camfis driven from thework shaft by suitable gearing f f 2 and acts against a lever h. Thefree end of this lever is by string z" connected to one end of a lever"Z, the other end of which is by string "Z connected to the rear end ofrack 6. Thus a revolution of the cam will cause the rack to bereciprocated, as will be readily understood. The rack e engages andrevolves a pinion -7', fast on a shaft 7;, having a hook-shaped end isand turning in bearings k of rail (Z. This pinion is placed somewhat infront of the lay, as shown in Fig. 1.

In front of the pinion j there may be arranged a second pinion Z, alsodriven by the rack and provided with a suitable cuttingdisk Z. Thispinion Z is only to be used if fringes are produced that are to have cutor open ends.

m is the shuttle, which I prefer to make of the construction shown inFig. (i-that is to say, it is provided with a pair of pins or rollers m,between which the weft it passes. This weft is gradually unwound from aspool a, secured to the loom, in contradistinction to a spool carried bythe shuttle itself. Thus the spool need not be thrown through the shedformed by the warp-threads 0; but each reciprocating motion of theshuttle will cause a sufficient length of thread to be unwound from thespool to form one loop or fringe.

The operation of the machine is as follows: The shuttle first moves tothe right and traverses the warp, beyond which it moves to form a loop,Fig. 8. Then the lay,with the shuttle, moves forward and backward tocause the loop to be enlarged by a finger t and to be engaged by thehook 713 Fig. 9. The shuttle next moves to the left, recrossing thewarp, while the loop is retained by the hook, Fig. 10. At this point thecam f causes the rack e to be moved backward, and thus the pinion j isrevolved to twist the loop into a twisted fringe r, Fig. d. Then theshuttle and lay move forward until a stop-pin s, secured to the lay,knocks the finished fringe off the hook, after which the spring 9 causesthe rack to be moved forward and into its original position, ready forthe formation of the next fringe.

Fig. 11 shows the position of the parts immediately before the pin 3knocks the fringe off the hook. The work passes around rollers 12 and isreceived by a suitable box 1).

To regulate the length of motion or stroke of the rack c, it is providedat one end with a head 6', moving between a pair of adjustable gages orstops it.

In ornamental or mixed fringes, in which twisted fringes alternate withplain fringes, the cams are so proportioned that the rack isreciprocated at the intervals at which the fringes are to be twisted.

What I claim is- 1. The combination, in a fringe-twister, of a shuttlewith a reciprocating rack, a pinion engaged thereby, and a hook securedto the pinion and adapted to engage the looped weft, substantially asspecified.

to the pinion, and with a pair of gages u, engaging the head 6',substantially as specified. 5. The combination of a reciprocating rackwith a pair of pinions engaged thereby, a hook 70, secured to onepinion, and a cutter Z, secured to the other pinion, substantially asspecified.
